I am able
to post my forms
to my database and I have stepped through my back end function
to check and see that my Get function is returning the same data I submitted. However I am having trouble understanding how
to have this data rendered upon visiting the page again. What am I missing? The intention is
to be able
to create, read, update, or delete (CRUD) some personal contact data for a variable collection of individuals.
